FASTEN ER FOR STAlR-CAR PETS.

SPECIFICATION forming part of Letters Patent No. 587,633, dated August 3, 1897. Application filed February 15,139'7- Serial No. 623,412. (No model.)

To all whom it may concern.-

Be it known that I, HARRY G. ADAMS, of New York city, in the county and State of New York, have invented a new and Improved Fas tener for Stair-Carpets, of which the following is a full, clear, and exact description.

My invention relates to an improvement in devices intended for fastening or holding stair-carpets in place which will readily permit of their being removed without removing the fastenings from the stairs.

The invention consists in certain parts and details and combinations of the same, as will be hereinafter fullydescribed and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the views.

Figure 1 is a perspective view showing one form of my device attached to the stairs. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is a perspective view of a short section of a modified form of the device, and Fig. 4 is a perspective view of a different construc tion of the same device.

My device consists, essentially, of two toothed bars or plates which are fastened one to the riser and the other to the tread near the junction of the same and with their toothed edges removed somewhat from the surface of the riser and tread and pointing toward the junction of the same.

In Fig. 1, A represents the tread of the stairs, and B the riser. A plate 0, which extends the greater part of the length of the step, is bent so that it will fit against the riser and This plate, as shown in Fig. 1, is made of a thin piece of metal. The edges of the plate are bent over, so as to form slight ledges, which turn backward and toward each other. To these ledges plates E are attached by rivets, screws, or other suitable fastening devices, as shown at cl. These plates along their inner edges are toothed, as shown at c, the opposing edges thereof being separated a slight distance from each other. In the drawings the size of the plates and of the fastener generally is shown proportionately larger than it would be in reality, the same being done for clearness of illustration.

In Fig. 3 the fastener is shown as made entirely of one piece 0 of thin sheet metal, the teeth e being formed directly upon the edges of the flanges E of the fastener.

In Fig. 4 bars or brackets O are shown bent in the proper shape and designed to be attached to the steps at suitable distances in the length thereof. To the ends of these plates E are attached by rivets or screws at the points cl.

In using my device the carpet F will be stretched upon the stairs and forced into the space between the opposing toothed edges of the fastener, as shown in Fig. 2. The teeth upon the plates E or the flanges E will engage the body of the carpet, so as to hold the same securely. It will also be possible when ever desired to readily disengage the carpet from the fastener for removal and without disturbing the attachment in any respect. This will make the use of the device much more convenient than the ordinary fastening devices. The plate 0 or the bars 0 whichever may be used, are fastened to the tread and riser of the stairs by screws D or other suitable devices passing through holes therein. The fastener maybe attached to any kind of stairs, whether of wood, iron, or stone. The device may also be made so as to be furnished cheaply, and will be of such a size as not to interfere with the width of the step.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A fastener for stair-carpets, comprising a bar having a serrated or toothed edge, and means for securing the same near the inner angle between the riser and tread, so that the toothed edge thereof projects across said angle, substantially as described.

2. A fastener for stair-carpets, comprising brackets or bars secured at intervals between the concave angle between the tread and riser, and toothed bars or plates secured thereto, with their toothed edges raised from the tread and riser and extending toward the apex of the angle between the two, substantially as described.

3. A fastener for stair-carpets, comprising between the toothed edges, substantially as two toothed bars or plates, and means connesting the same, whereby their toothed'edges project toward each other, the whole being 5 adapted to be secured in the inner angle between the riser and tread, and to secure the carpet by having, a fold of the same inserted described.
